[4] GENERAL TROUBLESHOOTING CHART
1. Indoor unit does not turn on
2. Indoor unit fan does not operate
3. Indoor unit fan speed does not change
Main cause Inspection method Normal value/condition Remedy
Cracked PCB.
(Cracked pattern)
Check visually. There should be no cracking in
PCB or pattern.
Replace PCB.
Open-circuit in FU1 (250 V, 3.15A). Check melting of FU1. There should be no open-circuit. Replace PCB.
Main cause Inspection method Normal value/condition Remedy
Refer to themistor temperature
characteristic
Replace thermistor.
Open-circuit in heat exchanger ther-
mistor (TH2)
Measure thermistor resistance
(dismount for check).
There should be no open-circuit
or faulty contact.
Replace thermistor.
Disconnected heat exchanger ther-
mistor (TH2)
Inspect connector on PCB.Check
thermistor installation con-dition.
Thermistor should not be
disconnected.
Install correctly.
